Arranged .to slideLinlth cylinder .1 0 is a rigid-Li against the pad prior to movement of the pad toward the shoe and then to sustain the shoe unyieldingly. In each end portion of the cylinder are a toe abutment I6 and a last abutment I'l each of which has the construction shown in sec'-. tion in connection with the toe abutment 15 in the lower end of the cylinder (Fig. 1). In each case the abutment is drilled to receive one end portion of a shaft I8 the other end portion of which is threaded through a curved bracket 80 and carries a hand-wheel 82. Each bracket 80 is mounted to swing on a pin 80 fixed in ears 85 secured to the side walls of the cylinder, the pin extending parallel to the longitudinal axis of the cylinder. The inner end portion of each shaft 18 is reduced in diameter to form a button 88 and a shoulder 90 between which is a pin 02 fixed in the abutment I6. On the shaft I8 between the abutment I6 and the bracket 82 is a compression spring Mwhich normally holds the button 38 against the pin 02 and permits the abutment to yield againstthe spring 9% to a limited extent. To prevent turning of the abutment, a plate or leaf spring 96 is secured to each abutment with its free'end resting against a flat face on the bracket 80.

Means is provided to connect with the atmosphere the end portion of the cylinder which may be uppermost and to exhaust the lower portion. For this purpose two air ducts I02 and I04 are provided, one leading irom each end portion of the cylinder to the trunnion I i fixed to the cylinder, the ducts extending longitudinally through the trunnion. A circular plate or disk I is mounted on the rear end of the trunnion I4 and fixed against rotation thereon by a pin IIII which is held in place by the head of a screw I08, the screw holding the disk on the trunnion. The duct 'I02leads through the trunnion I4 to the plate I06, where it connects witha radial groovefll I0 (Fig. 2) in the rearface oi the plate. The groove IIO leads into a semicircular groove I I2 which extends about the periphery of the plate I06 for nearly butnot quite a semicircumference. Theduct I04 leads groove IHI' communicating with a semicircular groove II similar to the groove I I2. 7

'Facing the disk I06 is a-di'sk II6 (Fig. 3) having a stem I8 mounted to slidelongitudinally in a bearing I (Fig. 1) formed in an extension I22of the frame I6. A key I24 is provided to prevent rotation of the stem I I8, and on the stem be tween the plate II6 and the bearing I20 is a compression spring I26 which holds the plate lit in frictionaL'air-tight engagement with the plate I06, Theplate II6 has two diametrically oppositeports I28, I30, the port I28 being open to the atmosphere and the port I30 being connected by a pipe I32 to an air pump I34 which will exhaustair from the. lower end of the cylinder, While the upper end is connected to the atmosphere through the port I28. With this arrangement, airis exhausted only from the end of the cylinder which is down, the upper end being always connected to the atmosphere through the in a similar manner to a radial port I28. Also, there will be sufficient friction of the piston in the cylinder to prevent its moving unless the air pressure is greater on one side than on the other. Moreover, exhausting the lower end of the cylinder will move the piston only until the piston covers the opening of the duct I02 or to the duct I04 if that is down.

In use, a shoe S with a sole 0 spotted thereon is placed on the pad I4. The abutments I6 and ,II are swung respectively about their pivots 8d over the last L and the forepart of the shoe, and the} hand-Wheels 82 are turned until the abutvments engage the work and the springs 94 are the pad. The coverte compressed enough to'hold the shoe firmly upon is then swung into closed position and secured in place by the swinging bolt 58. .The bolt 20 is released and the cylinder turned end for end on its trunnions until the bolt 20 engages the recess 24 in the cylinder. Early in this movement of the cylinder the duct I04 'is connected with the groove II2 leading to the pipe I32 which is the other end by the pump 34.

Connected to the trunnion I2 is a sandglass I36 which will be turned over when the cylinder is shifted end for end and will indicate, when' provided with the minimumtime during which the shoe should proper amount of'sand, the

remain under pressure;

Having thus described my invention, what I claim as new and desire to secure by Letters Pat- ,ent of the United States is:
